摘要

In a semiconductor charge transfer device circulating memory, the input control circuit to the device has the capability of either allowing the previous stream of charge packets either to continue circulating as the same information or of modifying the stream in accordance with a "write data" external signal, as each circulating bit passes from the output to the input charge storage site of the semiconductor charge transfer device. This invention involves the use of appropriately located integrated circuit transistor means for draining off excess electrical charges which have been found to accumulate at certain terminals in the input circuit, in order to suppress spurious error signals otherwise generated by these excess charges.
